I’m sure it has been said, but if not ...
With a little seniority on the 777, you can bid to have only one departure out of Memphis. Of course that is going to be a long trip (10-13 days or so). With good seniority you can have commercial airplane deadheads on the front and back of a trip. So you might not ever see Memphis except for training.
Last months bid pack had 30+ single departure lines. Because of the destinations (India for example) some of those go junior. The vast majority are two departure lines.
